To all svlwm it may concern:

Be it known that I, Camus J. B. Gums, of the city, county, and State ofNew York, have invented a new and improved- Eleeiro-Magnetic Engine; andI do.

hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to. the accompanying drawings,forming part of this specification. I, This invention relatesto new andimportantimprovements in eleotro-magrietio engines, whereby theyar'erendered more useful, as a motor?! than they have hitherto been; and

The invention consists in the construction; gement or parts, (but havingmore particular reference to an electro-magnefio ehgme invented byme,'and

- for which Letters Patent of the United States, bearing 7 date April 2,1867, have beengranted to me,) as will be hereinafter more fullydescribed. v

In the accompanying plates of drawings- 1' represents about elevation. I

cured to the bed. O is the shaft, which is supported by therframe B,'-inwhich it revolves. D is the armature-wheel, whichis firmly keyed to.

the middle of the shaft.

E represents the armatures, which are supported by the radiating arms,or spokes of the wheel D.

F represents the magnets, which are stationary, and radiate from hubs onthe frame B, which project inward from the stands, and which hubs aremarked G.

' iH is the distributing-wheel, which is placed loosely upon a bearingattached to the front stand of the frame. I is the circuit-breaker,which is a disk-wheel, or roll,

supported by an arm, J, which is attached to the shaft,

and revolves with it. In fig. l, '1' represents three metallic bars,which receive and transmit the electricity from one to the other sixpairs on each side of the wheel being shown in theexample of myinvention, with eight pairs of armatures attached to the wheel. Thesemagnets have a radial position, as shown in Figure 4, a verticalsectionof the distributing-wheel] The wire by which these magnets areeonnectedwith 'shown in fig. 1.

to which the magnets are attached. 7

The distributing-wheel H is provided with insulated metallic rings 1 Zl", the two former located upon opposite edges of the wheel, as shown infig. 2, and the latter upon the outer faced the same, as shown infig. 1.n n n represent a series of keys, insulated from faiegother, andconnected, respectively, to the rings connected with the post 8, toconduct the current of electricity, through the spring-aim Q, to thecircuit- 'breaker I.

--The operation is as fiallows: 1

The lower magnet, located in a similar manner upon the opposite side ofthe wheel, then receives the-cur barssecured tothe stand A and connectsthesame, by the wire 10. to-that magnet-which the same radialline. 4 :4v

' By thisfarrang'ement, itwillbe seen thatthetwo pairs armaturesnettothe battery, through the har :and 'post S.

- iAs' soon as the armatures be move, thelroll I also move in acorrespon egree, breaking the circuit through the key gz'and-rin'g l",and passing to one of the keys, n"; diredt'the current through the ring1'', and its corresponding magnets upon each side of the wheel. j

This operation is continued, as .the armatures are attracted andthewheei turned, to the keys n and ring Z, and their correspondingmagnets. The circuit, therefore, is broken and completed successively asthe roll I moves from one key to the other. By this means, a continuousrotary movement is given the wheel D. I The arm J which supports thecircuit-breaker,' or

the wheel, and thereby keep it incontact with the keys at all times.

The wires from the two poles of the battery are connected with-theengine by the two posts, or stands, marked 3 s.

The motion and power of the engine is conveyed by a belt from the pulleyT.

U represents a reversing-bar, attached to the dis- A- tributingewheel H,by which that wheel is moved or parthe positive pole of the battery isconnected at S, as

This is accomplished as follows: When the magnets and armatures are inthe relative positions shown in fig. 1, and it is desired to move thewheel 1) to the right, the distributing-wheel His moved, by means of thelever U, so as to direct the current/through that set of magnets whichare at the right of the armatures; and if it is uesired to move thewheel D in the opposite direction, the distributing-wheel is shitted, soas to direct the current through theset of magnets, at the left oftheirarmatures; and when it is desired to stop the rocation of thewheelD, the distributing-wheel H is so adjusted as to direct the currentthrough each set of magnets, when the armatures are directly over, orare just leaving them.

The velocityyith which the wheel is driven is regareas to the magnets,when the circuit is completed.

Having thus described my invention, I claim as new, and desire tosecure-by Letters Pa'tent- I The construction and arrangement of thestationary magnets, fixed upon the hub G, the revolving armaturessecured to the balance-wheel D, parallel to the axis thereof, and thedistrihuting-wheei H, loosely attaehed to the frame B, and madeadjustable, for the purpose of regulating the speed and changing thedirection of the revolving armatntes, by means of wires connecting itsinsulated keys and rings with the several sets of magnets, in the mannerherein shown and CHARLES J.
